Cannot open/create TM in one organization(Groupshare)

I suddenly cannot open/create TM in one of my organization/container.

below is my Groupshare org:

Organizaiton: Vendor A

    sub organization: SUB-1 (Container sub-1)

    sub organization: SUB-2 (container sub-2)

the user I used has administrator permission for all organizaitons.

when I access the TM page in website of groupshare for this sub organization "SUB-1" , it reports:"an error has occrured while processing your request." I cannot create TM in this organization either.

other organization SUB-2 TM creation and opening works fine.

Any one has the similar issue? how to resolve this? thanks.
